Conventional wisdom has it that Mosaic was the first graphical web browser. Even though Mosaic - the basis for Netscape - certainly kickstarted the web revolution, it wasn't the first graphical web browser at all - that honour goes to Erwise, developed by four Finnish college students in 1991. It was more advanced than Mosaic, ran on the X Window System, but didn't catch on in the end. The four developers recently gave an interview detailing Erwise and its history.
